T oalll whom it may concern l Be it known that I, FRANR S. WAL'roN',a

citizen of theUnited statesyi'esiding in Philadelphia, Pennsylvania, have invented an Improved Method ol-"Process of "Treating AutomObileTires and the Inner Tubes T hereof, of which the following isa specifi cation. a

My invention relates to the preservation of fibrous orfabric structures Withwhich rubber or a rubber-containing material may or may not be comblned; and the object of my invention is .to provide a special method of treating automobile tire shoes of 1am usual type receiving an inner inflatable tube, (the Walls of whichvtires are made up ofa plurality oflayers of fibers or fabric and rubber, and a cementitious body,)

for the purpose of lubricating and rendering pliable the fibers employed as well as for.

the, purpose of repelling aqueous moisture and reducing heat; thereby increasing the wearing properties of the tires and greatly reducing the danger of blow-outs due to the usual wear and tear to which they are subjected.

beneficial and preservative effect uponsuch inner rubber tubes.

way, although it canreadily be understood that under theconsta nt motion of the tire when in use, the strands of the fibers or fabric employed are being subjected to strains in all directions, with the result that sooner orglaterjthey give way, ,and the tire breaks down. Such condltion 1s recogn zed by all tlre manufacturers, and constant efforts are directed toward the production of a tire that will avoid this defect. The usual methods, so far as Iamadvised, have been to increase the weight of thefabric employed or to so manipulate the strands or fibers making up the same as to increase their strength and reduce their liability to break under the usual wear and tear accom panyingthe conditions of use. In all probability, the breaking down of the fabric. of atire is due to friction of the strands or Afurther object of my finvention is toefliect the preservationof the inner tubes of rubberennployed -with suc'lr tire shoes; the-materialemployed for the pun pose of preserving the tire shoes having a a stantiall non AND :THE INNER TUBES threads of the fibers or fabric employed, which are in constant motion when the tire isin use, du to the constant changing of the position of the same; such friction causing heat and rendering the strands and fibers of the fabric dry and brittle.

It is generally conceded that the fibers or strands of the fabric constituting the wall of the body or carcass of the tireshoe dry out,

become'broken, coarse in texture, and cause friction between the wall of the shoe and require the application of the lubricating medium to the inner surface of the tire shoe, 1t will come'in contact iVlth theinner tube and the latter will also be benefited; the lubricant providing a protective layer or coating for the same which reduces the fric? tion between the tube and the tire shoe.

Injmy Patent No.l,223,302, dated April 17 {1917,1 havedescribed the useof a non:

drying oleaginous body of animal origin whiclrmay be employed for the purpose, and itis essentialin the carrying out of the pro cess constitutingmyinvention that a sublrying or a semi-drying, oleag inous material, or a suitable combination of both, beemployed. 1 have discovered that beneficial results may now" from th'e' use of anyone of a number of non-drying or semi-drying oleaginous bodies of vegetable origin in use in the arts today, and my present invention comprises the treatment of tire shoes with a semidrying oleaginous vegetable body, such as castor oil, blown rape seed oil, or an equivalent semi-drying oleaginous vegetable body capable of performing the desired function, or a combination of two or more of the same, or any combination ofany nondrying or semi-drying oleaginous material with a non-drying or semi-drying oleagi- 1 Specification of Letters Patent.
